Just did the Tour of Flanders and Paris Roubaix Challenges on a CX-bike with Vittoria Hyper 35,s (run at 60 psi)and it worked out really well. The 35 mm tires gave me free choice of where I would ride the secteurs yesterday without any fear of a puncture. They feel much heavier than a road tire, but I had no problem riding with groups going at my normal speeds. I also suspect that on coarse and bad tarmac the Hypers are nearly as fast as skinnier tires. Being slicks you have to watch out cornering on gravel though ! I hope someone will make an affordable lighter large volume slick tire.

He shares his data, but I don't always agree with his conclusions. The data remains useful for making one's own choices.

There is a big difference between data and graphs. I like BQ, own several 650B bikes, and I like Jan's enthusiasm. But when I read BQ, I see tables and graphs, not data.

But when a company claims to make a 42mm tire with the same casing as their top-of-the-line racing tubulars, well, you have to try it. I honestly can't tell if they're any faster than the "standard" Hetres. They might be, but really, any advantage is lost in the noise of daily fluctuations in form, winds, phases of the moon, etc. They certainly are more comfortable than the standard version, which surprised me. The standard ones are already like marshmallows, but the Extra Legers do actually smooth out the ride even further. Are they worth the extra $20? Well, for me, yeah, I guess so. One more evolution and we'll be in $100/tire territory...
